Many folks don't know their Kwan lineage because it is not stressed.  The Kwans today in Korea function as fraternal societies which support the Kukkiwon curriculum 100%

Chung Do Kwan

in korea, i started in ohdokwan.  when i came to canada, i trained under songmookwan.  since 2001, haven't trained exclusively under one master. 

my master in korea being ex special force in military, he didn't focus too much on wtf sparring.  he taught us how to fight on the street - how to assess the situation, what to be aware of, what we can use to our advantage, etc. 

my master in canada had some gnarly calluses on his knuckles, and he put me through some kunckle strength training - makiwara board, and cement walls. 

since then, i've been training on my own or teaching others.  when i started university, i met up with some guys who had trained in other styles extensively, so we started training together, teaching each other one's own styles (boxing, judo, jiujutsu, wrestling, and muay thai).  4 of the guys currently are pro mma fighters, and we still train together. 

now, what i teach is based on what i've learned over the years.  how to think flexibly on the street (i.e., not getting hung up on certain self defense technique, but knowing basic idea of each techniques so that one can combine several appropriately for each situation) is main thing i teach.  one of the girls work at a group home where workers often get attacked, and she's been able to not only defend herself, but sending the right message to them without hurting them.
